- REVIEW
-
- The A64 Package is a hardware and software product. The hardware
- consists of a small box which has a male DB25 and 8 pin DIN connectors along
- with some special circuitry. This box connects to your parallel port and
- allows you to connect Commodore 8-bit serial peripherals such as the 15XX
- series disk drives and printers. NEVER PLUG THE INTERFACE INTO YOUR AMIGA
- WHILE THE AMIGA IS TURNED ON. You could damage your Amiga and peripherals
- by doing so. If you have an Amiga 1000 you will require an additional cable
- specifically made to connect A500/2000 devices to an A1000 parallel port.
- The hardware interface can stay plugged in at all times without interfering
- with any programs on your Amiga as long as they do not use the parallel
- port. If you want to use your parallel port with some other pieces of
- hardware like a printer or digitizer, you must either remove the hardware
- interface and install the other device or use an A-B switch box (Centronics
- parallel with female connectors).
-
- The software is a collection of Amiga programs which lets you access
- and run C64 software. The main program, A64, is the Commodore 64 emulator.
- The other programs allow you to transfer files between the C64 and Amiga
- disks (with 15XX disk drives).
-
- After you install The A64 Package and run the A64 program, you will
- notice that the BASIC startup screen is different from that of a real C64.
- This is because the Commodore 64 ROMs (two computer chips located inside a
- real C64 which contain the operating system) are not present in A64. The C64
- ROMs are not included because they are copyrighted by Commodore. The A64
- contains a complete C64 ROM emulation which allows A64 to run most C64
- programs. A64 ROM emulation is very compatible with the C64 ROMs, but there
- may be some C64 programs that will not run because of the lack of real C64
- ROMs. The A64 Package utilities includes a C64 BASIC program which can be
- transferred to a real C64 via a 15XX disk drive connected to the A64
- hardware interface. This program when run on the C64 will dump the C64 ROMs
- to a file which can then be transferred back to the Amiga and used in the
- A64 emulation.
-
- A64 is a complete Commodore 64 emulator. Sound, graphics, BASIC and
- machine language are all emulated. A64 fully integrates with the Amiga by
- allowing you to use Amiga disk drives, hard drives, ram drives, printers and
- modems.
-
- A64 operates in two modes: Pause Mode and C64 Mode. When in Pause
- Mode, you have access to the A64 Prefs (preferences) and A64Mon (machine
- language monitor). The current C64 program that A64 is running will be
- paused. Pause Mode gives you complete access to the Amiga system, and
- multitasking is completely functional. The C64 Mode runs the C64 program. In
- C64 mode you do not have access to the Amiga system. Multitasking is not
- disabled, but A64 controls a majority of the Amiga system. To enter Pause
- mode from C64 Mode, press the two ALT keys simultaneously.
-
- A64 emulation speed will depend on the program you are running and
- the type of microprocessor that your Amiga uses. On 68000 based Amigas, A64
- is not capable of running all programs at usable speed. Accelerated Amigas
- can see emulation speeds over 300%. Most games will not run over 100% no
- matter how fast your Amiga is.
-
- I've done most of my evaluation of A64 with public domain software.
- I have been able to run everything I can throw at it. I do enjoy browsing
- the ABCUG user group monthly C64 public domain program disk.
-
- A great deal of effort was spent trying to make the A64 as
- compatible as possible. The biggest problem with compatibility is related to
- disk I/O and custom disk drive routines. Custom disk drive routines "Fast
- Loaders" are extremely time critical and must run at exactly 100% speed in
- order to function properly. "Fast Loaders" vary from program to program. The
- only way to emulate "Fast Loaders" is to write a custom loader for each
- program which is impossible since there are hundreds of variations. A64 V3.0
- supports some "Fast Loaders" using Patch Files. There are Patch Files for
- ISEPICed archived programs, SID/PIC V3.4, SIDPlayer, and GEOS. (GEOS is
- supported only on 68000 Amigas and 1541/1571 disk drives because of the
- time-critical nature of the GEOS operating system.)
-
- One method of speeding up A64 emulation is to convert the C64
- program from 6510 opcodes to 68000 opcodes. This has the potential to double
- your emulation speed. This is accomplished with a utility called "CONVERT".
- The CONVERT utility converts C64 machine language into Amiga machine
- language. This conversion process eliminates a lot of work the A64 has do
- while running the emulation.
-
- A64Tools is the file transfer and file conversion utility. It allows
- you to copy, convert and print files using any combination of Amiga and C64
- disk drives and printers. Text files can easily be converted between
- PetASCII and ASCII. Amiga drives only support PRG and SEQ files under A64
- emulation. ":" and "/" are illegal characters for Amiga filenames. When
- A64Tools encounters on of these characters in a filename, the character will
- automatically be changed to a "-".
-
- As an original A64 V2.0 registered user, I am impressed with the
- enhanced SID chip support, increased speed and compatibility. I also welcome
- the addition of Patch Files for "Fast Loader" support along with support for
- GEOS. It was worth the $25 upgrade fee.

-
- DOCUMENTATION
-
- Documentations consists of a professionally printed softbound
- manual. It has an extensive index and table of contents. The manual assumes
- that you are familiar with the basic operation of the Amiga and the terms
- used to describe it. The manual also assumes you are familiar with the basic
- use of the Commodore 64.
-
-
- LIKES AND DISLIKES
-
- I like the professionally bound manual.
- I like the patch file support.
- I like the improved SID support.
-
- I dislike the software not working in native AGA graphic mode.
-
- I would like to see 1581 emulation using native Amiga disk drives.

-
- CONCLUSIONS
-
- I enjoy the ability to emulate other computers. As Newsletter Editor
- the ABCUG user group which supports the Amiga and Commodore 64/128 computer
- users, I find A64 a valuable tool for reviewing C64 public domain software
- and writing tutorials for the monthly newsletter. Understanding the
- limitations of software emulation, I give this product **** (4 out of 5
- stars).
